To satisfy and respond quickly to customers’ demand, many companies are now aggressively focusing on supply chain management in order to strengthen their competitiveness. This paper proposes an integrated business process reengineering (BPR) framework for improving performance. There are several steps in this framework: creating vision, identifying core processes to be redesigned, analyzing current core processes, designing for innovation, evaluating the new processes, selecting the best, and transforming and implementing the resulting design. A core process analysis matrix is proposed for identifying the critical processes. System simulation is useful in measuring the performance and predicting the effect of change on the system. To reduce the risk of BPR, an object-oriented simulation framework is developed for evaluating and analyzing the reengineering proposals. This paper uses a case study to show the value of the method.

Today, companies face severe competitive challenges. The agility of a company’s response to customer demand has been recognized as a critical success factor in meeting competition. Supply chain management (SCM) is an effective way to do this. The scope of a supply chain depends on the number of firms involved. Stronger and more sophisticated customer demands, increasing competitive pressure, and the ever-changing market environment are forcing companies to rethink the way they perform operations. One modern management strategy is business process reengineering (BPR). A number of similarities exist between BPR and SCM [10]. Both need fundamental rethinking and consideration of strategies and are process-based; also they generally reduce the duration of the processes. Of course, information technology is used as a catalyst for both. Supply chain reengineering aims to overcome the uncertainty associated with various aspects of the chain, including the changing needs and demands of customers, the quality of the information, and inherent delays that affect purchasing and ordering decisions.

A BPR framework and its associated implementing methods are proposed here and applied to the supply chain reengineering of a motorcycle manufacturer. A CPAM and the proposed OOS schema are integrated into the BPR framework. Once firms have decided on their business vision and objectives, they can identify the core business processes to be redesigned through the CPAM. Using the proposed object-oriented world-view simulation framework, firms can analyze and compare the probable influence of reengineering prior to its implementation to reduce high risks. It is very important that good communication exists between the business personnel collecting the data and the decision makers. Interaction is required in each step of the proposed framework. In conclusion, through the proposed BPR framework and associated implementing methods, we provide a systematic approach for industrial practice. Most importantly, the BPR framework takes advantages of the OOS, which can evaluate the reengineering in advance of the implementation, and this is expected to reduce the high failure rate of BPR projects.
